3.8 Camaro Timing Cover Gasket Replacement
Hello, so recently I have noticed the timing cover on my 3.8 (3800 motor) Camaro leaking coolant externally at an increasing rate. While replacing the gasket should be a straight process, let me explain where I'm nervous and uncertain...
Last year I had an old motor which developed rod knock, and I had attempted to replace the oil pump. However, I reassembled the timing cover twice and each time, immediately after startup got coolant in the oil. I am uncertain if the rod knock could've damaged the block, or I messed something up.
Fast forward, I have obtained a replacement motor that has been used. Everything else works fine, minus the external coolant leak. Now, assuming that nothing else is wrong with this motor, could coolant and oil mix through the timing cover if it is done improperly?
But mainly, what is the proper way to the very detail to replace the TC gasket? Where/what sealant do I use, dry gasket or RTV on gasket, and any other pointers I should be aware of.
